4.9 Two PVCs with ATM QoS Scenario
This tutorial shows you how to configure two PVCs and specify an ATM QoS type
for each PVC. In the following figure, the P-660HN-F1A is configured to transmit
two types of traffic, general data for Internet access and VoIP using SIP using 1/
33 and 1/34 PVCs respectively. General data is assigned Unspecified Bit Rate
(UBR) ATM QoS while VoIP traffic is assigned Constant Bit Rate (CBR) ATM QoS as
it is considered to transmit continuously.
4.9.1 ATM QoS and QoS Overview
Use the Network > WAN menus to create PVCs and apply UBR, CBR or VBR
ATM QoS to them.
Use the Advanced > QoS menus to identify individual packets, assign each
packet a priority and then queue the packet. Packets assigned with a high priority
are processed more quickly than those with low priorities if there is network
congestion.
